This effort continues the development of complete 3D printed nanosensors for in situ chemical sensing. The innovative 3D printing techniques developed by Professor Busnaina at Northeastern University will be leveraged to print patterns of nanomaterials such as carbon nanotube (CNT), graphene, and molybdenum disulfide directly on a daughter board. The device will then be functionalized and packaged at GSFC, and tested in GSFC's detector characterization lab. The small size, low power and high sensitivity of these sensors make them a game changing technology that can be used for a variety of space applications. Ultimately, the plan is to print other sensors such as temperature and pressure, as well circuits for wireless transmission of the sensor data, all on the same platform using the innovative 3D printing techniques.
